Radially through the tnbular melnber 18 adjacent its lower end opposed -'radial openings 20' are provided and extending from opposite sides "of the valve 5 are air outlet pipe's'21 with which the said openings 20 are'adapted to register throughopenings 21a formed in the'v'a lv'e-body "On the upper face otthe' lever-'7 a me1'nb e"1'" 22 is pivotally mounted. A bell c'rank23is pivotally' arranged on the'air valve One arm ot this'bell crank is pivoted to the-men? ber 22 and to its other arm a rod 24 is secured. The latter is so connected to the oil container spindle 11 that movement of the bell crank about its axis turns the said spindle. Thus when one extremity of the lever ings 2O register with the air outlet.pipes,2 1

Then compressed air passes through 'ainai'r" inlet pipe 25 into the tubular. member 18, and from the latter through the apertures 20;: and the. outlet pipes 21 which terminate iniejiectori nozzles "27., Th'ei latter are pref er-ablyz supported as by: a clip as shownat 271w: 'dependinglv. securedto" the g'uides 211, though any. othermethod'of supporting the saidsnozzlescmay be utilized; Connected to ea ch';of..-the latter is also one of thefeed pipes-13.

T Mounted on the base plate 2 is a bracket 30 by which a shaft 31 is rotatably supported. Rotatable on the shaft 31 is agear 32 hav-, ing a sprocket wheel 33 secured to one face thereof. Fixed on the shaft 31 is anarm' 34: and a lever 35, and carried byithe former is a dog 36 by which thesprocket wheel 33 and gear 32 are adapted to be turned in one direction and 35a. denotes a counterweight which, in the present instance, is integral with ,oneextremity of the lever A pinion 37 is rotatably supported by the bracket 30 and meshes with the ear 32, and 38 is a crankwhich is arranged to turnwith the said pinion.

- Dependingly supported from one s'ide of the base plate 1 is a U-shaped guide to hai ing opposed slots 41 extending longitudinally therethrough for the greater portion of its length. These slots are upwardly curved towards one extremity. A slide 42 is arranged between the adjacent sides of the glplide 40, and has pins 43 and 43a projecting t '0 hit a thgou th o sed slpts 41.

Slidable on the base plate 2 is a block 50 havinge'a roller-0 mounted thereon to engage the un'deiside of. the-outerextremity of tl1elever7.=;. -When thef=block-.is in the position indicated at 50a the oil-ia pertin'es 1.6 are moved-*outiofregistry-from the oil centainer outlets 3a,- and-the radial air valve openings 20 are abovethe-oiitiet connections 21: due to the raising ofthe lever 7' to its pm sition 7b. The block 50-is connected to the crank 38-by a connectingrod 52.

In order to prevent oil and grease from my device fallingonto the conveyor chain, indicated-at D in Figure (i -or onto work carried therebyI prefer to provide a housing consisting ofi twoopposed and substantially channel-shapedcasings;5et. The upper extremities ;of the latteri terminate adjacent one anothenq Theupper sides ofthese casings, which. are spaced above the top of the plate'2 and are mountedon T-shaped stands 55 extending upwardly from the said plate, are held relative to one another as by hooks 56. Adjacent theinnersides-of the casings 54c suitable absorbent. material 57 is provided which is held in place by wire netting 58.

59 denotes pinsby which the latter is maintainedin spaced relation to the casings 54L. 'lheeundersides 0t thecasings 54 are preterably positioned in alignm'entfwith the chain D and are made shorter than the upper sides to provide clearance for the said cha n.

From the foregoing it is believed that the operation of thedevi'ce will be readily un derstood; briefly it is as follows:

Each time the cams or trips 9 are raised by the passing of truck wheels 10 the stein 19 israised so that the air openings 20 register withthe outlets 21, sothat air then passes to the ejector nozzles 27; simultaneously by movement of the lever 7 to its position 70 the spindle 11 is turned so that the apertures 16 in the feed plate 12 are brought into registry with the outlet pipes 13. Oil in the said apertures is then drawn into the nozzles by the suction created by the air anddischarged therefrom against the bearings of the truck catedl 1 s p H If it is desired that the bearings be "only intermittently lubricated the lever 7 is raised "automatically to itsposition'7b on each alternate revolutionot the conveyor chain.

This is accomplished by providing a striker element C on one monorail truck B which actuates a member 44 and moves a slide from its normal position 5 .2 toits position 42a. This movement, through mechanism hereinbefore described, turns a pinion 37 through one-half a revolution and moves a block back and forth between its normal position and its position 50a. Thus each alternate time the slide 42 is moved to its position 42a it causes the block 50 to assumeits position 5Oa \vl1e1'eupo11 the lever 7 is raised to its inoperative position 7 b by the roller 60. When the lever 7 is-in its inoperative positlon 7b neither a1r nor oil can pass to the GJQCtOl nozzles 27' as hereinbeto're stated,

A am it willsbe seen-that when oil and air are discharged from the said nozzles the oilis in the form of spray, it'is therefore necessary, to protectthe work dependingly carried by the conveyor-chain D fromu'eceiving partof the sprayed oil, to utilize the casings 54; and by lining the latter with absorbent material 57 held in position by wire netting 58 it is found that the desired result is accomplishedn Moreover the ab sorbent material needonly be changed at relatively infrequent intervals.
